Date May 16, 1991.An electrode for providing TCET, especially via the earlobes of the patient, comprises an electrical conductor for application to the skin, connected to a lead for supplying the TCET signal from a signal generating device, characterized in that the conductor comprises a generally conical needle point capable of penetrating the epidermis so as to provide good electrical contact over a very small area. The electrode can be used in the impedance of less than 100 k OMEGA ; and with apparatus for generating an electrical signal for use in TCET, adapted to provide a signal at a current of less than 200 mu A (0.2 mA), especially when adapted to provide an AC signal in which each positive pulse is relatively short and high without being spiked and the following negative pulse is relatively wide and low, the total amount of positive and negative charge being balanced. Methods of providing TCET treatment to patients using the electrode and apparatus are also provided.
